2002IAUC.7999....2H

Hamuy also reports that a spectrum of SN 2002ha (cf. IAUC 7997), obtained as above on Oct. 25.03 UT, shows it to be a type-Ia supernova about 3 days before maximum light, very similar to SN 1994D. A narrow interstellar Na I D absorption line at the redshift of the host galaxy can be seen with an equivalent width of 0.1 nm. Hamuy adds that a spectrum of SN 2002gy (cf. IAUC 7996), obtained on Oct. 25.21, bears resemblance to the type-Ib/c SN 1999ex. A prominent absorption at rest wavelength 614 nm can be seen, which could be due to Si II 635.5-nm or high-velocity H-alpha. A narrow interstellar Na I D absorption line at the redshift of the host galaxy is present with an equivalent width of 0.32 nm, which suggests significant reddening.
